DollaTek 28BYJ-48 ULN2003 5V Stepper Motor + ULN2003 Driver Board for Arduino - 5pcs

• Stepper Motor is a type of electromagnetic device which moves in discrete steps.
• This has several coils, the center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately given current or not, creating magnetic fields which repulse or attract the magnets on the shaft, causing the motor to rotate.
• This Unipolar Stepper Motor 28-BYJ48 is provided with five wires and four coils. The center connections of the coils are tied together and usually used as the power connection.
• They are named unipolar steppers because power always comes in on this one pole.
• A, B, C, D four-phase LED indicates the status of the stepper motor work.Stepper motor with a standard interface, when used directly pluggable.

Description: BYJ48 Stepper Motor This Unipolar Stepper Motor 28-BYJ48 is provided with five wires and four coils. The center connections of the coils are tied together and usually used as the power connection. They are named unipolar steppers because power always comes in on this one pole. A, B, C, D four-phase LED indicates the status of the stepper motor work. Stepper motor with a standard interface, when used directly pluggable. 5 line 4 phase can be used for ordinary ULN2003 chip driver, connect to the 2 phase , support the development board, with convenient use, direct docking.
